Ok, thanks. I'll have to lab that one up. I have always assumed that
it needed to be on the same subnet.

Hi dave,
this was once discussed a few weeks ago. You can do this with ip
unnumbered loopback 0' provided you introduce the loopback 0 of both
routers into area 0. Doing so, we have just extended the area 0 on to
the far end router.

Doesn't this tunnel have to be an assigned ip address that is on
the
same subnet (both ends of the tunnel)? And, this subnet would
then have
to be assigned to area 0. Can this even be done with ip
unnumbered?

Be sure to read the wording of the lab carefully. They may (or
may not)
allow you to create additional IP addressing within a certain
scope, as
needed.
Using ip unnumbered to a loopback isn't all that great of an
idea, as
your
loopbacks will generally be in different subnets.

Using another subnet address is extra commands and is not a good
idea.
That's my opinion.
